The thing is with sticking things to moveable objects, Blockland currently doesn't have a clean, good looking way to do so.
As for players, one would think an image would be enough, but that doesn't show the sticky thing on the place of impact.
As for constantly setting the place of something in a loop, that would eat processing power when a couple of people would be stickied.
It simply isn't done because as far as most people know, there isn't a good way to do so.
But prove me wrong.
I would be happy to accept that.
